I am a Research Associate in the Income and Benefits Policy Center of the The Urban Institute. My research addresses and evaluates social insurance and welfare programs, especially Social Security Disability Insurance, Supplement Security Income, and Unemployment Insurance. I am particularly interested in how economic circumstances, income sources, and program characteristics influence program participation for displaced and disabled workers. My other research interests include technological change and employment prospects of workers, the wage effect of immigration reform, and how family arrangements are affected by unemployment.
